My 13-year journey spans the entire systems spectrum, evolving from low-level runtimes to massive, high-throughput distributed infrastructure.

I started my career engineering distributed payment transaction servers for a rural payment gateway, where I had to ensure absolute data consistency and fault tolerance across unpredictable networks. I then moved deep into real-time operating systems (RTOS) at GE, mastering client-side data integrity and memory constraints.

I scaled this foundational discipline into extensive, high-traffic distributed architectures: first at Imperva, co-engineering highly concurrent, low-latency SaaS DDoS defense engines using DPDK to process data at line-rate; and most recently at Netskope, architecting cloud-native Data Loss Prevention (DLP) pipelines in Go that handle hundreds of millions of asynchronous events via Redis streams and Kubernetes pods.

What Makes Me Unique Distributed Systems & Security Craftsmanship: I don't treat security like a compliance checklist. Because I deeply understand concurrency, distributed state, and Linux internals in C++ and Go, I build airtight encryption, privacy barriers, and access controls directly into high-traffic architecture without introducing lag.

AI-Native Execution: I operate with a modern velocity multiplier. I design custom AI prompt loops and automated testing agents to relentlessly threat-model complex distributed workflows, catching race conditions and system vulnerabilities at double the speed of a traditional developer.

Employment History

Staff Engineer at Netskope Current 2025 - Now
Architecting High-Volume Data Pipelines: Design and develop distributed, cloud-native Data Loss Prevention (DLP) microservices in Go, capable of processing hundreds of millions of asynchronous real-time events. Distributed Systems Management: Build and manage highly concurrent service architectures utilizing Redis streams for high-speed event streaming and deploy them as resilient, auto-scaling workloads inside Kubernetes pods. Advanced Cryptography & Key Management: Secure sensitive cloud data by architecting end-to-end decryption workflows, safely fetching AES and public-private key pairs from HashiCorp Vault to decrypt high-volume data assets stored in AWS S3. Performance Optimization: Maximize backend execution speed and eliminate system bottlenecks, ensuring that deep security inspection and data masking operate with minimal latency.
Lead Application & Network Security Engineer at Imperva 2022 - 2025
Engineering Line-Rate DDoS Defenses: Co-engineered high-performance, SaaS-based DDoS mitigation and rate-limiting infrastructure capable of handling hundreds of millions of requests under active global attack vectors. Kernel Bypass Optimization: Utilized DPDK (Data Plane Development Kit) to bypass Linux kernel overhead, optimizing the network stack for raw line-rate packet processing and ultra-low latency. High-Performance C++ Development: Designed and maintained highly concurrent, thread-safe network pipelines in C/C++ tailored for multi-core Linux platforms to prevent memory leaks and performance degradation. Real-Time Threat Mitigation: Developed and optimized inline traffic inspection modules and pattern-matching algorithms to detect and deflect network-layer attacks instantly without slowing down legitimate user traffic.
Technical Lead R&D at Altran(Capgemini) 2019 - 2022
Real-Time Systems Development: Designed and implemented low-level, high-reliability software architectures in C/C++ on real-time operating systems (such as QNX RTOS) and embedded Linux platforms. HMI & Client-Side Engineering: Co-engineered robust, intuitive Human-Machine Interfaces (HMIs) using the Qt framework, focusing on smooth UI rendering and low-latency response times for safety-critical systems. Resource & Memory Optimization: Ruthlessly optimized memory management pipelines, eliminated runtime memory leaks, and managed strict hardware constraints where CPU and RAM footprints were severely limited. Telemetry & Data Integrity: Developed fault-tolerant local data storage mechanisms and secure logging pipelines to handle critical system telemetry without degrading core execution performance.
Technical Lead at Harman Connected 2018 - 2019
Platform & Middleware Engineering: Designed and developed high-performance middleware and core platform services in C/C++ running on embedded Linux and real-time operating systems. Networking & Connectivity Protocols: Implemented and optimized secure network communication stacks, IPC (Inter-Process Communication) mechanisms, and data-routing layers to ensure reliable data transfer between distributed system components. System Architecture & Device Hardening: Built robust device-level security features, including secure data transmission, access controls, and encryption protocols, protecting system integrity against local and remote vulnerabilities. Linux Internals & Performance Tuning: Conducted deep-dive debugging of multi-threaded application behavior, optimized CPU/memory utilization, and resolved complex race conditions or resource bottlenecks within the Linux user-space and kernel boundaries.
Software Engineer at GE Transportation ( A Wabtec Company) 2015 - 2018
Mission-Critical C++ Development: Designed and developed core application modules and control-plane logic in C++ for real-time operating systems (RTOS) and industrial embedded Linux platforms. HMI Architecture & Qt Engineering: Engineered robust, low-latency Human-Machine Interfaces (HMIs) using the Qt framework, ensuring deterministic UI performance and real-time visualization of safety-critical telemetry data. Telemetry Logs & Data Integrity: Developed fail-safe, highly optimized local data storage mechanisms and event-logging subsystems to capture and store high-frequency locomotive diagnostics reliably. Safety-Critical System Hardening: Implemented rigorous multi-threaded safety barriers, handled strict memory boundaries, and eliminated race conditions to prevent system crashes or vulnerabilities in high-stakes environments.
Senior Software Engineer at mVikarsha 2012 - 2015
Architecting Distributed Payment Servers: Designed and co-engineered the core distributed backend server infrastructure for a specialized rural payment gateway framework, ensuring robust system reliability from the ground up. Data Consistency & Fault Tolerance: Engineered strict transactional boundaries and crash-recovery logic to guarantee absolute data integrity (ACID compliance) and prevent partial failures over unpredictable, low-bandwidth network environments. High-Throughput Concurrency: Implemented highly concurrent, multi-threaded server-side logic to process high volumes of financial transaction requests originating from distributed mobile agents and Point of Sale (POS) terminals. Secure Transaction Routing: Integrated secure communication protocols, cryptographic hashing, and data encryption wrappers to safeguard sensitive financial data and personal credentials during transit and processing.
